Too many startup items

[zman818]

As I add startup items, I often start slamming into the following...

Cannot open '____'. A critical component is either missing or cannot start because program memory is unavailable. <snip>

Soft resets clear it, though oftentimes I'll have to do it repeatedly to get a completely clean boot (if I don't feel like starting the skipped app manually). Different apps get caught up in it at different times. For example, it might be s2u2 on one boot and aebuttonplus on the next. The more startup apps I add, the more often it seems to happen... sometimes to multiple apps in a boot.

Everything is on device storage, so it has nothing to do with the availability of storage card memory.

Any thoughts on specific cause and more importantly, a solution that doesn't involve trimming the # of startup apps? TIA.
